Mitigation Goal

• Interim goal of 2,290 hatchery-origin adults above LMO annually from NPTH production

• Long-term goal of 3,750 hatchery-origin adults

above LMO annually from NPTH production • Provide ~1,000 adults annually for broodstock • Develop early returning run to the Selway and S.F.

Clearwater Rivers

Management Objectives • Develop, increase, and reintroduce natural populations

of early-fall, and fall Chinook in the Clearwater River Basin.

• Sustain long-term preservation and genetic integrity of target fish populations.

• Keep the ecological and genetic impacts of non-target fish populations within acceptable limits.

• Provide harvest opportunities for Tribal and non-Tribal anglers.

Juvenile Release Targets

• FCS goal: 1.4M release • 500K sub-yearlings from NPTH into

Clearwater River

• 500K sub-yearlings from North Lapwai Valley AF into Clearwater River

• 200K sub-yearlings from Lukes Gulch AF into S.F. Clearwater River

• 200K sub-yearlings from Cedar Flats AF into Selway River

M & E Objectives • Determine if program targets for contribution rate of

hatchery fish are being achieved and can be improved.

• Estimate ecological and genetic effects to fish

populations. • Determine how harvest opportunities for early-fall,

and fall Chinook salmon can be optimized for tribal and non-tribal anglers within Nez Perce Treaty lands.

• Effectively communicate monitoring and evaluation

program approach and findings to resource managers.

Brief Program History

• Hatchery production began in 2002.

• Broodstock development and collaborative program with Lyons Ferry Hatchery (LSRCP and IPC).

• Working out the kinks with new facility reaching full production.

• Expanding from main NPTH and North Lapwai Valley releases to upstream acclimation releases.

Fish Health Highlights

• Injections of female broodstock with erythromycin three weeks before spawning

• Ovaplant (sGnRHa) pellet injection to accelerate egg maturation in unripe females

• Lower levels of culling for Bacterial Kidney Disease

• Bacterial Gill Disease outbreaks greatly reduced (cooler incubation and rearing temperatures)

Adaptations in response to identified problems

• Ovaplant injections to unripe females. • Cooler incubation and early rearing.

temperatures – No Bacterial Gill Disease. • Changed incubation cleaning protocols. • North Lapwai Valley early releases. • North Lapwai Valley instream water supply
